Write complete, balanced equations for all cases in which a reaction takes place

Question

Write complete, balanced equations for all cases in which a reaction takes place. Your observation that a reaction occurred would be by a color change, by the formation of a gas, by the formation of a precipitate, or y releasing heat. In cases showing no evidence of a reaction, write No Reaction. Classes of chemical reactions Combination reactions Observation Decomposition reactions What happens to the glowing splint? What gas was produced. Color of precipitate produced by remains of test tube 1 mixed with AgNO2 The formula of the substance remaining after heating KIO3

Explanation / Answer

1. 2Mg+O2-> 2MgO. It presents light and high temperature

2. (NH4)2CO3 ? 2 NH3 + CO2 + H2O. 3. It is a decomposition rxn. It produces gases as CO2 and NH3.

4. - KIO3 + AgNO3-> KNO3 + AgIO3. AgIO3 does not solve in water.

- KI + AgNO3 -> AgI + KNO3. AgI does not solve in water.

5. I do not know what there was in the test tub 1.

6. 2KIO3 (HEAT) -> 2KI +3O2(g).
